HOT-WATER HEATING SYSTEM.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed November 9, 1914. Serial No. 871,193.

To all whom t may concern:

Be it known that I, FERDINAND LANG, a subject of the Russian Empire,residing at Colorado Springs, county of El Paso, State of Colorado, haveinvented certain new and useful Improvements in I-Iot-lVater HeatingSystems, of which the following is a specication.

This invention relates to hot water heating systems, and its object isto provide a novel and improved means for establishing a circulation ofthe water, together with a connection which permits the heating of waterin a stand boiler for domestic purposes.

The herein-stated objects are attained by means of 'a combination andarrangement of parts to be hereinafter described and claimed, referencebeing had to the accompanying drawing in which- Figure 1 is an elevationof the boiler; Fig. 2 is a central vertical section thereof; Fig. 3 is aplan view, and Fig. 4 is a horizontal section on the line 4-4 of Fig. 2.

In carrying out the invention there is provided a sectional boiler, theunits or sections 15 of which are superimposed and constructed andarranged to form communicating water chambers around flues and smokechambers which carry the smoke, hot gases and other productsl ofcombustion. lEach section 15 comprises a cylindrical shell 14,horizontal top and bottom plates 14It and 14h, respectively,constituting the upper and lower faces of the section, an intermediateplate 14n, and a vertical flue 36 extending between the top andintermediate plates and opening therethrough. In the center of the topYplate is an upstanding nipple 32, and at the center of the intermediateplate is a depending nipple 33. A cylindrical wall 33@l extendsconcentrically and in spaced relation with the shell 14, between thewalls 14b and 14C, thus forming an annular water space which is incommunication with the water chamber formed by the shell 14 and thewalls 14c and 14a. In assembling the sections, the bottom nipple 33 isscrewed into the top nipple of the next section below, the nipples beingscrew-threaded for this purpose, and the sections are so assembled thatthe flues 36 are alternately on diametrically opposite sides of thevertical center line of the sections, inorder that the products ofcombustion may have a tortuous path. When the sections are thusassembled an annular smoke chamber is produced between the top wall 14aof a section and the intermediate ,wall 14c of the next section above,the side Walls of this chamber being the wall 33@- of the upper chamberand the nipples connecting the sections, whereby the smoke chamber issurrounded by the aforementioned annular water space. The flue 36a opensat its lower end into this smoke chamber and its upper end opens intothe next smoke cha mber above, and from the last-mentioned smoke chambera flue 36 connects with the nextgsmoke chamber above, but on theopposite side, and so on throughout the entire series of sections. Theproducts of combustion therefore take a tortuous path and a largeheating surfacey is produced, resulting in a rapid heating of the waterand consequent fuel economy. The water circulates from one section tothe next through the nipples connecting the same at the center.

The shell 14 of each section 15 is reduced near the top to form anexternal shoulder, and the bottom of the section has a dependingexternal annular flange 34 of a diameter to fit snugly around the upperend of the shell of the next section below, and of a length to seat onthe shoulder thereof, to make a tight connection between the sections. Aclean-out door 8 is also provided.

At 5 is indicated the fire-pot of the boiler, the same being mountedover an ash pit 1, and provided with a feed door 7, a clinker door 6 anda grate 2, supported on seats 3.

The ash pit has a door 4. The fire-pot isvk Y closed at the top by adome 5a and is surrounded by a water leg 15a. Above the dome is a waterspace which communicates with the water space 15a and with the waterchamber of the lowermost one of the sections 15 through the bottomnipple 33 of said section. Smoke flues 36a extend through the waterspace above the dome and connect the fire-pot with the smoke chamber ofthe lowermost section.

The section which forms the top of the boiler has a smoke chamber 11,and above the latter a water chamber 16. A flue 36b connects the chamber11 with the smoke chamber of the section 15 next to the top section, andthe water chamber of the lastmentioned section is connected by nipples32a to the water chamber 16.

The water chamber 16 has outlets 13 leading to the radiators, and anoutlet 17 con- ,nected to the water space 15a.

nected to the top of a reservoir 16a'in the form of an ordinary standboiler mounted alongside the boiler. On the other side of the boiler isa similar reservoir 15b. VThe reservoirs are mounted on suitablesupports 22. The reservoir 15b has a connection 29 -at the top with thewater chamber of the section 15 next to the top section, and at thebottom a connection 24 with the water space 15a. rlhe reservoir 16a hasa connection 19 at the bottom with the water space 15a, with a` valve 2Oin said connection. By reason of these connections a circulation throughthe reservoirs is established. The water passes into the reservoir 15bfrom the water chamber of the section 15 next to the top one and flowsback to the water space 15a. The water in the chamber 16 passes into thereservoir 16n and flows back into the water space 15a.

In the nipple connection 32a is a valve 35 provided with an operatinghandle 12 on the outside of the boiler. This valve is for the purpose ofcutting off communication between the water chamber 16 and the waterchamber below to which the reservoir 15b is connected, so that thecirculation through the reservoir 16a may be cut off.

The return 21 to the boiler from the radiators is connected to thereservoir 16a at the bottom thereof. The water chamber 16 has aconnection 30 with a safety valve or shockabsorber. To the reservoirs15b and 16a are connected thermometers 28. The reservoir l15b has anoutlet 27 at the top, and a washout 25 at the bottom, provided with avalve 26.

To the smoke chamber 11 is connected an outlet 10 provided with a damper12 for regulating the draft. A cold draft door 9 is also provided, thesame being in line with the outlet 10.

lThe cold water supply inlet to the sections 15 is indicated at 28, thesame Vbeing cona When the heating system is in use the water pressure isleft on. Y

The reservoir 16a is designed to hold the eXtra amount of water requiredfor the heating plant, and the reservoir 15b is for the purpose ofsupplying hot water for the kitchen, bath, laundry.I etc. If the heat inthe heating plant is to be reduced, the valve 2O can be closed,whereupon the water for the heating plant will still circulate throughthe reservoir 16"L and also through the pipes 13, and then the heat canbe regulated by the valve 35. rThe heating system can alsoy be entirelycut out by closing the valves 35 and 20, whereupon the water circulatesthrough the reservoir 15b only. lf all the hot water should be takenfrom the reservoir 15", this will not affect the heating plant becausethe intake 28'will force water through the sections 15 onlyand outthrough the corresponding pipes 29 and 211, and the water in the chamber16 and the reservoir 16a will not be affected until the water in thesections is again heated up.

l claim:

1. A water-heater for hot water heating systems having connections tothe heating units of the system, a circulation reservoir mounted outsidethe heater and having connections with the top and bottom thereof, avalve in the bottom connection, and a return vfrom the heating unitsofthe system connected to the reservoir. Y

2. A water-heater for hot water heating systems, said heater havingseparate water chambers, a hot water reservoir mounted outside theheater and having circulating connections with one of the waterchambers, outlets from the other water chamber to the heating units ofthe system, a circulation reservoir mounted outside the heater andconnected to the second-mentioned water chamber, and provided with avalved return connection to the heater, a return from the heating unitsof the system connected to the reservoir, and a valved connectionbetween the water chambers.
